It is often said that the eye is the window to one’s soul, early data suggests that retinal photos may become that window used as an early detector of Alzheimer’s disease. The preliminary results of an Australian pilot study were unveiled in Paris yesterday at the International Conference on Alzheimer’s Disease. Not many details were released however it appears that retinal photographs were used to determine the ratio of the diameter of the retinal arteries to the retinal veins (called the A/V ratio). The investigators then found a positive correlation between the A/V ratio and the amount of beta amyloid deposits in the brain. Beta amyloid deposit or plaques are known to exist in higher concentrations in patients with Alzheimer’s disease.

If further study of this correlation confirms the author’s findings then this could lead to an inexpensive and relatively easy way of giving patients and doctors an early indicator of which patients are more likely to later develop Alzheimer’s Disease.

Results from a pilot study conducted by doctors at the New England College of Optometry were recently presented at Optometry’s Meeting and the American Academy of Optometry. In the study, subjects were examined using the methods of traditional ophthalmoscopy and optomap® assisted ophthalmoscopy, where an ultra-widefield retinal image from the Optos P200C guides the BIO fundus examination.

Forty subjects underwent non-mydriatic imaging with the P200C. Subjects were then dilated and underwent traditional ophthalmoscopy and optomap® assisted ophthalmoscopy. The traditional exam consisted of BIO and slit lamp biomicrosopy with precorneal lenses. optomap® assisted ophthalmoscopy was identical to traditional, with the exception that the doctor reviewed optomap® Images before performing their BIO examination. A masked Reader graded the optomap® Images of all subjects. A retinal specialist examined 28 of the 40 subjects and served as the gold standard. Continue reading →

The Doctors is a TV show carried on CBS featuring four doctors that discuss current medical topics and new technologies. And yes one of the doctors you may recognize as “The Bachelor”. Recently they featured the technology of the optomap® Retinal Exam. Total Eye care is one of approximately 3000 offices nationwide that utilizes this great technology. Check out the video below. For more information on the Optomap Retinal Exam check out the Total Eye Care website.
